Working Principle

The AOT20C60L is an n-channel MOSFET and works on the principle of a majority carrier device. It has an intrinsic semiconductor body with a lightly doped n-region at the source and drain. Between these two n-regions lies the heavily doped p-region which serves as the gate. When voltage is applied to the gate, it attracts electrons from the source and creates an electric field between the source and drain. This electric field makes it easier for majority carriers, which are electrons, to move from the source to drain, resulting in current flow. The device is highly efficient because of its low RDSON, which is the resistance of the device when it is in the on-state. It also has a high safe operating area (SOA) which prevents it from overloading in heavy current applications.

Conclusion

The AOT20C60L is an n-channel MOSFET that is used in a wide range of applications because of its low power consumption and fast switching speeds. Its low RDSON and high SOA make it highly efficient and able to handle high currents. It finds use in power electronics, audio amplifiers, cellular base stations, high voltage converters and infrared control systems. It works on the principle of a majority carrier device wherein an electric field is created between the source and the drain due to the attractive property of voltage applied to the gate.
